find the value of x?

1. 7x+3=10x-9

2. 4x+6=6x-3 - Apr 6th 2008, 06:22 PMtopher0805
You are supposed to post new question in new threads....but I'll answer it anyways.

1.) $\displaystyle 7x+3=10x-9$

Add 9 to both sides:

$\displaystyle 7x+12=10x$

Subtract 7x from both sides:

$\displaystyle 12=3x$

Divide both sides by 3:

$\displaystyle x=4 $

2.) $\displaystyle 4x+6=6x-3$

Add 3 to both sides:

$\displaystyle 4x+9=6x$

Subtract 4x from both sides:

$\displaystyle 9=2x$

Divide both sides by 2:

$\displaystyle x=\frac {9}{2}$ - Apr 6th 2008, 06:25 PMMathstud28You can say
that their measures are equal...as well as
